11 6462as?atarm?03-jun-09 AT91SAM9G10 5. power considerations 5.1 power supplies the AT91SAM9G10 has six types of power supply pins: ? vddcore pins: power the core, including the processor, the memories and the peripherals; voltage ranges from 1.08v and 1.32v, 1.2v nominal. ? vddiom pins: power the external bus interface i/o lines; voltage ranges from 1.65v to 1.95v and 3.0v to 3.6v, 1.8v and 3.3v nominal. ? vddiop pins: power the peripheral i/o lines and the usb transceivers; voltage ranges from 2.7v and 3.6v, 3.3v nominal. ? vddbu pin: powers the slow clock oscillator and a part of the system controller; voltage ranges from 1.08v and 1.32v, 1.2v nominal. ? vddpll pin: powers the pll cells; voltage ranges from 3.0v and 3.6v, 3.3v nominal. ? vddosc pin: powers the main oscillator cells; voltage ranges from 3.0v and 3.6v, 3.3v nominal. the double power supp lies vddiom and vddiop are identified in table 4-1 on page 10 . these supplies enable the user to power the device differently for interfacing with memories and for interfacing with peripherals. ground pins gnd are common to vddcore, vddiom and vddiop pins power supplies. sep- arated ground pins are provided for vddbu, vddosc and vddpll. the ground pins are gndbu, gndosc and gn dpll, respectively. 6. i/o line considerations 6.1 jtag port pins tms, tdi and tck are schmitt trigger inputs and have no pull-up resistors. tdo and rtck are outputs, driven at up to vddiop, and have no pull-up resistor. the jtagsel pin is used to select the jtag boundary scan when asserted at a high level (tied to vddbu). it integrates a permanent pull-down resistor of about 15 k to gndbu, so that it can be left unconnected for normal operations. the ntrst pin is used to initialize the embedded ice tap controller when asserted at a low level. it integrates a permanent pull-up resistor of about 15 k to vddiop, so that it can be left unconnected for normal operations. 6.2 test pin the tst pin is used for manufacturing test purposes when asserted high. it integrates a perma- nent pull-down resistor of about 15 k to gndbu, so that it can be left unconnected for normal operations. driving this line at a high level leads to unpredictable results. 6.3 reset pin nrst is an open-drain output integrating a non-programmable pull-up resistor. it can be driven with voltage at up to vddiop. as the product integrates power-on reset cells, the nrst pin can be left unconnected in case no reset from the system needs to be applied to the product.
12 6462as?atarm?03-jun-09 AT91SAM9G10 the nrst pin integrates a permanent pull-up resistor of 100 k minimum to vddiop. the nrst signal is inserted in the boundary scan. 6.4 pio controller a, b and c lines all the i/o lines pa0 to pa31, pb0 to pb31, and pc0 to pc31 integrate a programmable pull-up resistor of 100 k . programming of this pull-up resistor is performed independently for each i/o line through the pio controllers. after reset, all the i/o lines default as inputs wi th pull-up resistors enabled, except those which are multiplexed with the external bus interface signals that require to be enabled as peripherals at reset. this is explicitly indica ted in the column ?reset state? of the pio controller multiplexing tables. 6.5 shutdown logic pins the shdn pin is an output only, driven by shutdown controller. the pin wkup is an input only. it can accept voltages only between 0v and vddbu.

14 6462as?atarm?03-jun-09 AT91SAM9G10 7.2 debug and test features ? integrated embedded in-circuit emulator real-time ? two real-time watchpoint units ? two independent registers: debug control register and debug status register ? test access port accessible through jtag protocol ? debug communications channel ? debug unit ?two-pin uart ? debug communication channel interrupt handling ? chip id register ? ieee1149.1 jtag boundary-scan on all digital pins 7.3 bus matrix ? five masters and five slaves handled ? handles requests from the arm926ej-s, usb host port, lcd controller and the peripheral dma controller to internal rom, internal sram, ebi, apb, lcd controller and usb host port. ? round-robin arbitration (three modes supported: no default master, last accessed default master, fixed default master) ? burst breaking with slot cycle limit ? one address decoder provided per master ? three different slaves may be assigned to each decoded memory area: one for internal boot, one for external boot, one after remap. ? boot mode select option ? non-volatile boot memory can be internal or external. ? selection is made by bms pin sampled at reset. ? remap command ? allows remapping of an internal sram in place of the boot non-volatile memory ? allows handling of dynamic exception vectors 7.4 peripheral dma controller ? transfers from/to peripheral to/from any memory space without intervention of the processor. ? next pointer support, forbids strong real-time constraints on buffer management. ? nineteen channels ? two for each usart ? two for the debug unit ? two for each serial synchronous controller ? two for each serial peripheral interface ? one for the multimedia card interface

16 6462as?atarm?03-jun-09 AT91SAM9G10 a first level of address decoding is performed by the bus matrix, i.e., the implementation of the advanced high performance bus (ahb) for its master and slave interfaces with additional features. decoding breaks up the 4 gbytes of address space into 16 areas of 256 mbytes. the areas 1 to 8 are directed to the ebi that associates these areas to the external chip selects ncs0 to ncs7. the area 0 is reserved for the addressing of the internal memories, and a second level of decod- ing provides 1 mbyte of internal memory area. the area 15 is reserved for the peripherals and provides access to the adva nced peripheral bus (apb). other areas are unused and performing an access within them provides an abort to the master requesting such an access. the bus matrix manages five masters and five slaves. each master has its own bus and its own decoder, thus allowing a different memory mapping per master. regarding master 0 and master 1 (arm926 ? instruction and data), three different slaves are assigned to the memory space decoded at address 0x0: one for internal boot, one for external boot, one after remap. refer to table 8-3 for details. each slave has its own arbiter, thus allowing a different arbitration per slave. 8.1 embedded memories ? 32 kb rom ? single cycle access at full bus speed ? 16 kb fast sram ? single cycle access at full bus speed table 8-1. list of bus matrix masters master 0 arm926 instruction master 1 arm926 data master 2 pdc master 3 lcd controller master 4 usb host table 8-2. list of bus matrix slaves slave 0 internal sram slave 1 internal rom slave 2 lcd controller and usb host port interfaces slave 3 external bus interface slave 4 internal peripherals
17 6462as?atarm?03-jun-09 AT91SAM9G10 8.1.1 internal memory mapping table 8-3 summarizes the internal memory mapping for each master, depending on the remap status and the bms state at reset. note: 1. ebi ncs0 is to be connected to a 16-bit non-volatile memo ry. the access configuration is defined by the reset state of s mc setup, smc pulse, smc cycle and smc mode cs0 registers. 8.1.1.1 internal sram the AT91SAM9G10 embeds a high-speed 16-kbyte sram. 8.1.1.2 internal rom the AT91SAM9G10 integrates a 32-kbyte internal rom mapped at address 0x0040 0000. it is also accessible at address 0x0 after reset and before remap if the bms is tied high during reset. 8.1.1.3 usb host port the AT91SAM9G10 integrates a usb host port open host controller interface (ohci). the registers of this interface are directly accessible on the ahb bus and are mapped like a standard internal memory at address 0x0050 0000. 8.1.1.4 lcd controller the AT91SAM9G10 integrates an lcd controller. the interface is directly accessible on the ahb bus and is mapped like a standard internal memory at address 0x0060 0000. 8.1.2 boot strategies the system always boots at address 0x0. to ensure a maximu m number of possibilities for boot, the memory layout can be configured with two parameters. remap allows the user to lay out the first internal sram bank to 0x0 to ease development. this is done by software once the system has booted for each master of the bus matrix. refer to the bus matrix section for more details. when remap = 0, bms allows the user to lay out to 0x0, at his convenience, the rom or an external memory. this is done via hardware at reset. note: memory blocks not affected by these paramete rs can always be seen at their specified base addresses. see the complete memory map presented in figure 8-1 on page 15 . the AT91SAM9G10 bus matrix manages a boot memory that depends on the level on the bms pin at reset. the internal memory area mapped between address 0x0 and 0x000f ffff is reserved for this purpose. if bms is detected at 1, the boot memory is the embedded rom. if bms is detected at 0, the boot memory is the memory connected on the chip select 0 of the external bus interface. table 8-3. internal memory mapping address master 0: arm926 inst ruction master 1: arm926 data remap(rcb0) = 0 remap (rcb0) = 1 remap (rcb1) = 0 remap (rcb1) = 1 bms = 1 bms = 0 bms = 1 bms = 0 0x0000 0000 int. rom ebi ncs0 (1) int. ram c int. rom ebi ncs0 (1) int. ram c

26 6462as?atarm?03-jun-09 AT91SAM9G10 10.3 peripheral multiplexing on pio lines the AT91SAM9G10 features three pio controllers, pioa, piob and pioc, that multiplex the i/o lines of the peripheral set. each pio controller controls up to thirty-two lines. each line can be assigned to one of two peripheral functions, a or b. table 10-2 on page 28 , table 10-3 on page 29 and table 10-4 on page 30 define how the i/o lines of the peripherals a and b are multiplexed on the pio control- lers. the two columns ?function? and ?comments? have been inserted for the user?s own comments; they may be used to track how pins are defined in an application. note that some output only peripheral func tions might be duplicated within the tables. the column ?reset state? indicates whether the pio line resets in i/o mode or in peripheral mode. if i/o is mentioned, the pio line resets in input with the pull-up enabled, so that the device is maintained in a static state as soon as the re set is released. as a result, the bit corresponding to the pio line in the register pio_psr (peripheral status register) resets low. if a signal name is mentioned in the ?reset stat e? column, the pio line is assigned to this func- tion and the corresponding bit in pio_psr resets high. this is the case of pins controlling memories, in particular the address lines, which requ ire the pin to be driven as soon as the reset is released. note that the pull-up resistor is also enabled in this case. 10.3.1 resource multiplexing 10.3.1.1 lcd controller the lcd controller can interface with several lcd panels. it supports 4, 8 or 16 bit-per-pixel without any limitation. interfacing 24 bit-per-p ixel tfts panel prevents using the ssc0 and the chip select line 0 of the spi1. 16 bit-per-pixel tft panels are interfaced through peripheral b functions, as color data is output on lcdd3 to lcdd7, lcdd11 to lcdd15 and lc dd19 to lcdd23. intensity bit is output on lcdd2, lcdd10 and lcdd18. usin g the peripheral b does not prevent using the ssc0 and the spi1 lines. 10.3.1.2 ebi if not required, the nwait function (external wait request) can be deactivated by software, allowing this pin to be used as a pio. 10.3.1.3 32-bit data bus using a 32-bit data bus prevents: ? using the three timer counter channels? outputs and trigger inputs ? using the ssc2 10.3.1.4 nand flash interface using the nand flash interface prevents: ? using ncs3, ncs6 and ncs7 to access other parallel devices 10.3.1.5 compact flash interface using the compactflash interface prevents: ? using ncs4 and/or ncs5 to access other parallel devices
